Heli days, Schluter junior 50, OS 50 engine and had drilled the throttle linkage slightly out through the bulkead........ bend the push rod a bit , will be fine, just fine.

Rod kind of does not like new shape, so keeps exerting sideways pressure on throttle arm on carb which is a press fit........

Arm duly comes off in hover mode 3 foot above ground, the barrel on the carb rotates to fully open, engine at full bore, PANIC PANIC. Modle briskly accelarates and climbs to about 8 foot.

Pull the stick back, no effect on throttle still full power, full hastily applied negative pitch, very spectacular crash, not much left of the mechanics, me too close spattered in shrapnel and debris[:@]

Made redundant following week, 2 years to repair!!!

Done the aileron thing on sons park foamy GWS 109. Got away with it problems at 15 feet but managed to cut throttle and with some luck belly landed with no damage save for wheels....... but then launched again as had not worked out what problem was!!!! In bits, son in tears, gets home[sm=thumbup.gif] Know what the problem was.... son not speaking for 2 days![X(]
